ESPEN GuidelineESPEN guidelines on definitions and terminology of clinical nutrition
Introduction
Nutrition plays a pivotal role in life and in medicine. Acute and chronic diseases in most organ systems have pronounced effects on food intake and metabolism with increased catabolism, which lead to nutrition-related conditions associated with increased morbidity and eventually death. At the other end of the spectrum, diet is a major determinant of future health, i.e. the absence or postponement of disorders like cardio-vascular disease, diabetes, cancer and cognitive disease [1].
In order to handle nutritional challenges during disease, trauma, rehabilitation, and elderly care as well as for the nutritional prevention of disease it is essential to use professional language and standard terminology that is founded on evidence and widely accepted in the professional community. However, this is not always the case. For example, concepts and terms of nutritional disorders in the current International Classifications of Diseases (ICD-10) (http://www.who.int/classifications/icd/en/) may not always be consistent with modern understanding or terms commonly used in clinical practice and research.
Therefore, it is important for the nutritional practice and research communities, including dietitians, nurses, pharmacists, physicians and scientists as well as their respective scientific associations, to reach consensus on the terminology and criteria to be used for nutritional disorders as well as for core nutritional procedures such as screening, assessment, treatment and monitoring. A unification of the appropriate terminology would enhance the legitimacy, credibility and comparability of nutritional practices and could also support future updates of disease and procedure related classification systems, such as the ICD system. This may lead to improvements in clinical care and the advancement of the clinical and scientific nutrition fields.
These aims led the European Society for Clinical Nutrition and Metabolism (ESPEN) to appoint a Terminology Consensus Group with the mission to provide such a set of standard terminology with a main focus on adults.

Aim and selection of the expert group
Part of the continuous work of ESPEN is to produce guidelines that support improvements in clinical care and facilitate research. In 2014 new standards for setting ESPEN Guidelines were established [2]. The presented Guideline standard operating procedures (SOP) aimed to generate high quality guidelines using a clear and straight-forward consensus procedure, with one of the goals to establish international leadership in creating up-to-date and suitable-for-implementation guidelines. To provide
Nutritional concepts
Nutrition science deals with all aspects of the interaction between food and nutrients, life, health and disease, and the processes by which an organism ingests, absorbs, transports, utilizes and excretes food substances [4]. [Strong Consensus, 97% agreement]
Human nutrition addresses the interplay of nutrition in humans. Preventive nutrition addresses how food intake and nutrients may affect the risk of developing disease such as cardiovascular disease (CVD), obesity, type 2 diabetes mellitus
Discussion
This definition and terminology consensus statement presents an up-dated overview of terminology of core nutritional concepts, procedures and products. The purpose was to identify relevant nutrition terminology used in routine nutritional practice and research, to describe that terminology and when feasible to give diagnostic or descriptive criteria. Another objective was to identify gaps in the nutritional terminology and to provide consensus based and when possible evidence based definitions
